SIGMUND BERGHANN AND CHARLES J. KLEIN, OF NEWV YORK, N. Y.; SAID KLEINASSIGNOR TO SAID BERGMANN.

INSULATING COUPLING-BLOCK AND CUT- OUT.

SPECIFICATION forming part of Letters Patent No. 446,180, dated February10, 1891.

Application filed March 11, 1890. Serial No. 343,536. (No model.)

To all whom it 11mg concern:

Be it known that we, SIGMUND BERGMANN and CHARLES J. KLEIN, residing atNew York, county and State of New York, have invented a certain new anduseful Improvement in Insulated Coupling-Blocks and Gut-Outs, of whichthe following is a specification.

'lheinvention relates to combined insulated coupling-blocks and cut-outsadapted to connect a fixture to a gas-pipe.

The object is to connect a fusible cut-out with a coupling-block in suchmanner that the whole may be contained in a small space and wherebyelectric wires leading to a lamp may be easily attached to the mainwires.

\Ve will describe an insulated couplingblock and cut-out embodying ourinvention and then point out the novel features in a claim.

In the drawings, Figure l is a side View of a device embodying ourimprovement. Fig. 2 is a plan or bottom view of the cut-out, and Fig. 3is a top view of the device. Fig. dis a vertical section.

Similar letters of reference designate corresponding parts'in all thefigures of the drawings.

Referring by letter to the draw1ngs,Adesignates a coupling-blockconsisting of the two sections a a, havingthe usual insulating material(0 between them and secured together by means of screws a The screws apass through insulated openings in the section a and engage with tappedholes in the section a. The section a is provided with aninternally-threaded tubular boss a to engage a gas-pipe projectingthrough a wall or ceiling, and the section a is provided with a similarboss a to engage a fixture.

B designates a disk of insulating material-- such as hard rubber oranalogous material having a central opening to pass over the boss a onthe section a, and the disk is secured to the insulating-block by meansof the screws o Pairs of connecting-plates b are secured on the outerside of laterally-extending portions of the disk B by means of screws b,and a bindingpost b is placed at'each end of the respective plates 79.The adjacent ends of each pair of plates b are electrically connected bya fusible wire cut-outb We have shown the fusible cut-outs as solderedor otherwise connected to yoke-plates 12 which are clamped underadjacent binding-posts 19 Main wires 0' pass through openings 0 in thelaterally-extended portions of the disk B and engage with outerbinding-posts b and wires 0 lead from the other binding-posts b to alamp. Of course the relative positions of the wires may be changed and agreater number of connections than that shown may be employed. 7

Having described our invention, what We claim is In a coupling-block andcut-out, the combination of a section havinga tubular boss to engage apipe, another section havinga tubular boss to engage a fixture,insulating material between said sections, a disk of insu1ating materialhaving a central opening to pass over the boss of the last-namedsection, the said disk extending laterally beyond said sections andhaving openings for the passage of main wires outside of the sections,screws passing through the disk and sections securing the partstogether, pairs of connecting-plates secured to the disk on its outerside, bindingposts on the plates, and fusible wires, substantially asspecified.
